Elvis is Richie and Eddie's pet goldfish. In "Apocalypse," Elvis is floating dead in his bowl on the dining room table, however it is unclear how he died. Richie plans to use Elvis's death as leverage for getting money from his Auntie Olga, by suggesting that they've had to kill him just so they can have something for their tea.

In "Dough," Elvis's bowl is still on the dining table, and is used by Richie to extinguish his trousers when Eddie sets them on fire.
